The NuSTAR view of the non-thermal emission from PSR J0437-4715
Sebastien Guillot, Victoria M. Kaspi, Robert F. Archibald +11
We present a hard X-ray NuSTAR observation of PSR J0437-4715, the nearest millisecond pulsar. The known pulsations at the apparent pulse period ~5.76 ms are detected at energies up…
NuSTAR Observations of Magnetar 1E 1048.1-5937
C. Yang, R. F. Archibald, J. K. Vogel +5
We report on simultaneous NuSTAR and XMM-Newton observations of the magnetar 1E 1048.15937 obtained in July 2013, along with Rossi X-ray Timing Explorer (RXTE) data for the same…
Modelling of the Surface Emission of the Low-Magnetic Field Magnetar SGR 0418+5729
Sebastien Guillot, Rosalba Perna, Nanda Rea +2
We perform a detailed modelling of the post-outburst surface emission of the low magnetic field magnetar SGR 0418+5729. The dipolar magnetic field of this source, B=6x10^12 G estim…
Phase-resolved NuSTAR and Swift-XRT Observations of Magnetar 4U 0142+61
Shriharsh P. Tendulkar, Romain Hascöet, Chengwei Yang +12
We present temporal and spectral analysis of simultaneous 0.5-79 keV Swift-XRT and NuSTAR observations of the magnetar 4U 0142+61. The pulse profile changes significantly with phot…
The Dense Matter Equation of State from Neutron Star Radius and Mass Measurements
Feryal Ozel, Dimitrios Psaltis, Tolga Guver +3
We present a comprehensive study of spectroscopic radius measurements of twelve neutron stars obtained during thermonuclear bursts or in quiescence. We incorporate, for the first t…
